hosts entries, so comments are not processed.
Last few touchups & shrinkage for this round.
Current score:
install.sh+install.sub+upgrade.sh = 36,934 (vs 40,062 for 3.2).

Use value of 'hostname' to store all HOSTNAME and FQDN information. Elminate
those global variables. For install accept user input as is, but if the short
form hostname is unchanged, save any domain info by not re-setting hostname.
For upgrade just set hostname from /tmp/myname.
Unconditionally create default hosts file in install.sh, rather than doing it
in separate places depending on whether or not the user configures the network.
Always ask if the user wants to edit the hosts file when the network is
configured, but without listing it out.
Don't put 'search' command in resolv.conf as we now set hostnames to include
fully qualified domain names, which will be used to yield local domain name.
Loop asking for the default route until the user enters one that 'route'
accepts or the user explicitly asks for no default route by entering 'none'.
Add FQDN info to hosts file just before saving configuration files to the
installed system. Preserve user added lines - those with aliases or with domain
information in the hostname.
Clean up donetconfig() logic. Delete network config files in install.sh so that
if the user restarts an interrupted install previous network configuration does
not leak into installed system.
Elminiate get_resolv_fqdn(), searching resolv.conf for domain info only when
dhcp was used. get_fqdn() is reduced to looking for domain info in current
hostname, and supplying 'my.domain' if none found.
Add save_comments() and use to preserve useful comments in the installed
/etc/hosts and /etc/dhclient.conf files. Previous logic for dhclient.conf could
cause repeated appending of configuration info rather than just preserving the
comments.
Cleanup logic copying files from /tmp to /mnt/etc, eliminating unneeded
cfgfiles variable. Use wildcards and subshells to shrink code size.
|
|
Redo configure_ifs() to take full advantage of recent code
refactoring, and cleanup code while there.
Move address or dhcp question to after media option handling so that
each question gives immediate feedback. i.e. if the media options
given don't work then say so and exit, and if dhcp is requested
immediately issue the dhcp request. Also allows some code shrinkage.
Eliminate addifconfig() and remount(). The former is folded into
configure_ifs() and the latter's three lines simply replace the call
in install.sh.
Move remount code to before any configuration files are moved to the
installed system.
|
|
Create dhcp_request() and use in configure_ifs() rather than repeat code. When
dhcp is successful, move /etc/dhclient.conf, /etc/resolv.conf.tail to /tmp, and
use normal configuration file installation to put them on the installed system.
Also apply any user specified media options immediately. If they don't compute
then return immediately.

avoid problems with the single bpf interface available on install
media.
Move umount'ing of filesystems to the start of any install or upgrade
execution.
Eliminate now vestigal cleanup_on_exit() and all associated traps.
Shrinks scripts, makes more reliable, improves intuitiveness of
re-running install or upgrade, eliminates an install/upgrade time
message, leaves filesystems available if install/upgrade script
interrupted.

same time as we ask for the default route and name server addresses.
This allows users to override any DHCP supplied domain information the
same way they could override DHCP supplied default route and name server
addresses. As a result, remove the now superfluous warning about
not supplying information DHCP is going to overwrite.

descibing how the fstab will be used follows immediately after the
fstab listing, and the paragraph explaining about editing the fstab
comes immediately before the offer to edit the fstab. Eliminate a
blank line before the question as it is now tightly related to the
paragraph that precedes it.

returns false, and the device is *not* added to DEVSMADE.
|
|
Eliminate the function get_setsdir() by merging it into
install_mounted_fs(). Eliminate global SETSDIR as a result.
Move the loop logic used to select the directory to use on a mounted
filesystem to a 'done' style loop. i.e. loop until valid input (a
directory which exists) or 'done'. 'done' implies abandoning effort to
find a directory.
Eliminate the test for and associated error message about no
filesystems being mounted below the mount point passed to
install_mounted_fs(). This served little purpose not addressed by the
message generated when a non-existant directory is entered. i.e.
novices won't understand and experts can '!' out to investigate.
Remove the option to list mounted filesystems. Same reasons as for
eliminating the test for mounted filesystems.
Move repeated tests for an empty GET_FILES into the function
invariably called after the tests (install_get_files()).
|
|
1) When asked to choose a device, a user could enter two identical
words separated by a blank (e.g. 'a a') and thereby confuse the check
for selection validity. Quote user response before using it.
2) When asked to choose a sub-timezone, the user could escape to
a shell and when returning only see half the sub-timezone prompt
redisplayed. Put entire prompt into ask() parameter rather than
displaying first half in a separate echo -n.
Also change a "(or done)" to "(or 'done')" to be consistant with
other similar displays and move the initial comment for mount_a_disk()
to before the function to conform to normal usage.

logic. As result, MDSETS gone from everything but mac68k.
MDSETS now treated as a list of complete file names to add to THESETS,
allowing more MD flexibility, i.e. may or may not be .tgz files.
All traces of tar.gz removed. Not used for sets since 2.7 or so. As a
result of code simplification from not having to consider tar.gz, the
functions get_sets(), make_lastset(), and set_not_done() are
eliminated, along with the global SETS.
Build THESETS and DEFAULTSETS to contain full file names.
Always install sets in the order they appear in THESETS, keeping
siteXX last but without needing special logic. More predictable for
user if a lot of set additions and removals done before being
satisfied, as the sets are now installed in the same order they appear
in the selection list.
Remove ability to look for non-set .tgz/.tar.gz files. The job of the
install scripts is to install the standard sets in a simple and
rational way. Not to install general tar balls. The user can do that
post-install or simply '!' out to do it during install. On their head
be it.
If no sets are found in a specified source, list the filenames in
THESETS to show what is being looked for.

set. Just re-display the selection list unchanged. Smaller, cleaner.
|
|
|
|
this pass check the file list returned by ftp_list_file() for two
common errors ('Login failed.' and 'No such file or directory.') and
display the error messages rather than just complaining that no sets
were found.
Delete an unused local variable.
Do not allow the user to continue with the install/upgrade if the
sanity checks fail. Keep asking them to install more sets until the
checks succeed.
ok millert@.

1) Do all three sanity checks (for bsd, base32, etc32) every time so
the user is aware of all three problems asap. Make the error messages
stand out, and refer explicitly to the sets that should fix the
problem.
2) Use standard 'done' logic to exit the set selection loop rather than
ask a separate question. One side effect: a <cr> at the set location
prompt now just causes the redisplay of the prompt rather than an
error.
3) Remove 'suspect' sets from the SETSDONE list so that if bsd, base32
or etc32 are found to be wanting, they are automatically selected the
next time they appear on the list of available sets.
4) But the $MDSETS (and therefore the 'bsd' set) first on the
selection list. This puts all three 'required' sets at the top of the
list where they seem to belong.

installed.
This should guarantee that any site-specific files which are intended
to replace files installed from 'normal' sets will do so.

Every system has a name, and thus generated keys with that
name, even if there is no currently configured network.
So, ask for a system hostname before configuring the network.
Eliminate /tmp/myname and just keep hostname set to the lastest name
and FQDN.
Construct /etc/myname from hostname as configuration data is being
saved. Construct /etc/hosts (preserving the informative leading comment
from the /etc/hosts file in etcXX.tgx) at the same time.
Construct an appropriate /etc/hosts file even if the network is not
configured.
During upgrade, if the user enables the network using the existing
configuration, don't ask about the domain name - just use the
configured one.
Take care to handle existing /etc/myname files which do not necessarily
have a FQDN.
Originally problem with hostname handling pointed out by beck@.

devices, to allow ask_which() to be used for interface configuration.
Rework network interface configuration logic to use ask_which() instead
of local code. This
1) May fix the problem noted by David Norman, where the prompts are
somehow broken, since no such problems have been noted with the
ask_which() code.
2) Shrinks the install output by a few lines.
3) Makes the install script smaller and clearer.
4) Makes interface configuration consistant with other 'device'
configurations.
5) Makes it impossible for a user to configure an interface more than
once.
Add the interface name to the 'IP address (or dhcp)' question. This
makes it more informative, especially if a '!' or '!foo' shell escape
has been used and overwritten the list of interfaces and the display of
the name of the one being configured.
|
|
1) If the user escapes to a shell with '!' or executes a command with
'!foo' at a prompt then repeat the prompt when the shell or command
returns.
2) If ask_which() is passed an empty list of devices , then set resp to
'done' and return. Replaces a couple of checks before calling
ask_which(). Also emit a message about the lack of devices.
3) In ask_which(), delete any trailing blank which rmel() may have
appended to the device list. Replaces a check before calling
ask_which().
4) Remove an unneeded blank line before the 'invalid choice' message
from ask_which().
5) Make the first disk device the default answer when asking for which
disk contains install sets.
A few code/verbiage nits:
1) make _a a local in cutlast().
2) use normal ': ${_defdev:=done}' idiom instead of an or condition in
ask_which.
3) Eliminate an unnecessary blank line/paragraph by putting 3(!)
sentences into a single paragraph when describing process of selecting
install sets.
4) Eliminate another unnecessary blank line between the list of
possible install sources and the question about which one to use.
5) Eliminate another unnecessary blank line before the 'Extract
more sets?' question
6) Eliminate a double blank line after the sanity check error
messages.
ok deraadt@.

by implementing the rules:
Only '/' is neither nodev nor nosuid. i.e. it can obviously *always*
contain devices or setuid programs.
Every other mounted filesystem is nodev. If the user chooses to mount
/dev as a separate filesystem, then on the user's head be it.
The only directories that install puts suid binaries into (as of 3.2)
are:
/sbin
/usr/bin
/usr/sbin
/usr/libexec
/usr/libexec/auth
/usr/X11R6/bin
and ports and users can do who knows what to /usr/local and sub
directories thereof.
So try to ensure that only filesystems that are mounted at or above
these directories can contain suid programs. In the case of
/usr/libexec, give blanket permission for subdirectories.
Note that if *all* the above are split into separate filesystems the
install process will attempt a couple of cross-device links when
installing base32.tgz, and fail.
ok deraadt@.

separating items.
This allows a compaction of the displayed lines for device selection.
Customize the device selection routine so the actual device type is
shown (disk or CD-ROM). Rename ask_fordev to ask_which so the
invocations (with device type) read better.

$ROOTDEV and ${ROOTDISK}b can be used for swap. Also shortens output
generated during (successful) install.
Fix problem with upgrade on systems with many disk devices by
automatically creating devices encountered during the fsck'ing of fstab
filesystems. Problem noted by Dethlef Madsen and Nick Nauwelaerts.
Adjust some verbiage in i386 install.md to make it more consistant.
Reformat welcome message to make sure all lines are <80 characters wide.
Minor cleanups.

the install example will easily fit on the CD insert at some
reasonable font size. Reword many messages and questions for same
reason.
In addition:
1) Add '...done.' to match 'Installing boot block...'
2) During install, after asking which is the root disk, start
initializing it immediately rather than asking again which disk to
work on.
3) Move munged fstab filesystem mounting to *before* network
initialization so that if you bail out during network initialization
and restart you do not have to go through disk initialization again.
Also puts fsck and mount messages close to each other rather than
spitting out the latter just before root password questions.
4) Make 'usr/obj' nosuid,nodev by default, /home nodev by default.
5) For network interfaces only show the complete list of media options
if the user indicates they want to change the default.
6) Move the question about the ftp server supporting passive ftp to
*after* selecting the ftp server where it is more 'rational' and can
easily be made more concise.
7) Don't bother umount'ing filesystems or stopping the dhclient after
a successful install/upgrade. The next step is a reboot after all.
Some minor code tweaks and comment cleanup while in the area.
Tested in recent snapshots. Suggested by & ok deraadt@.

routine to install.sh so it is displayed only once.
Strongly advise /, /tmp, /var, /usr and /home have their own
disk partitions as requested by deraadt@.
Rather than rely on users not re-selecting an already initialized
disk, just allow them to choose from un-initialized disks.
Move get_root invocation into install.sub as both install.sh and
upgrade.sh did it first thing.
Remove the 'workaround' to a 'vnode aliasing bug' that came in
with the initial import of upgrade.sh from NetBSD. ok millert@.
Rework verbiage in a few places. Clean up logic around looping
through disk units by handling root disk better.
|
|
1) Correctly sort >10 total partitions.
2) Don't allow user to specify duplicate mount points via
disklabel.
3) Fix mount point checking so that empty mount points
do not confuse logic.
4) Fix mount point checking so that duplicate mount points
from previous disk initialization are correctly detected.
5) Show configured partitions/mount points in partition order
(i.e. sorted by disk and then partition) rather than mount
point order. This seems easier to read to me and reflects the
order of user action. Sort the entries after user approval.
6) Clarify, clean up some verbiage and logic.
|
|
1) Fix 'already mounted' checking so a mount point name can be the same
as the leading substring of a previously specified mount point.
Now you can specify /usr after /usr/obj, and since the mount points
are sorted before writing to fstab, it should work.
This also fixes the error message generated when a requested mount
point matches the leading substring of multiple mount points. e.g.
trying to mount '/' again.
2) Fix fstab sorting so that it works across all initialized disks, not
just on a disk by disk basis.
3) For additional paranoia during multiple disk installs, unset _partitions,
_psizes, and _mount_points before processing a disk. Eliminate individual
blanking of _mount_points entries.
4) Shorten/simplify logic by storing ${DISK} in _partitions entries rather
than always adding it back in when referencing _partitions.
5) Rework verbiage a bit, eliminating the duplicate display of configured
devices before making new filesystems.
Some code clean up, eliminating '{}'s, better loops, ifs, etc.

to it. Fixes mount point prompts during install.
'Improve' an error message.
Noted by todd@ and jsyn@.
|
|
Do not allow the same mountpoint to be specified for >1 disk
partition.
If a mountpoint that has already been specified is entered again an
error message of the form:
Invalid response: sd0a is already being mounted at /var
is emitted. Partitions on both the disk being initialized and
previously initialized disks are checked.
Rework a bit of the logic to simplify and shorten in compensation. e.g.
eliminate references to /tmp/fstab.<disk> as it is never created.
|
|
1) Even if /sbin/mount_nfs is present, do *not* try to automatically
mount nfs file systems. Because not all name resolution mechanisms are
present during upgrade (e.g. yp) it is not safe to do so. The user
must manually mount nfs file systems if they are the source of any
sets. Problem noted by miod@, change seconded by deraadt@.
2) Change initial verbiage so that a brief introduction is displayed,
along with the information about !foo or !, before the terminal type
is requested. After the terminal type is known display the rest of
the introductory text using less -XE. This belts and suspender fix
makes both the install and upgrade text fit in 'page' size (<24 lines)
chunks and ensures that if the text ever grows beyond a page a more
informative prompt is displayed. Problem noted by millert@.
